7.1 Summary

The USPACK is a package of auto-scaling routines with the main purpose of providing a simple method for creating a graph for data. The main functions of this package are:

1.: To check the maximum and minimum values of the data and to set appropriate transformation function parameters.
2.: To calculate appropriate intervals for tick marks and labels for the current transformation function, and to plot the coordinate axes.

The routine for plotting coordinate axes in (2) can be called independently, so it can be used as an utility to draw coordinate axes quickly. It is convenient when used with the UDPACK for drawing contours.

The actual polylines are dependent upon the UUPACK, and the coordinate axes and titles upon the UXPACK/UYPACK.
